Determine a substrates true energy content

The AMPTS II Light allows users to determine the biomethane potential, anaerobic biodegradability and dynamic degradation profile of any biomass substrate. This in turn will allow users to select and price a substrate according to its true energy content of biomass, thus helping to ensure a good control of substrate economy for biogas plants.

The AMPTS II Light is a well-engineered instrument developed for biogas plant operators for the rapid evaluation of biomethane or biogas potential from various biomass substrates. The AMPTS II Light will allow operators to fully explore the biomethane or biogas potential of all available substrates and make better business decisions based upon the true value of a substrate.

Compare your results and reports

The AMPTS II Light supports all anaerobic biodegradability, biochemical methane potential (BMP) and specific methanogenic activity (SMA) test protocols, allowing for the standardisation of measurement procedures, data interpretation and reports. In addition to providing automatic gas volume measurements and data logging, significantly reducing time, labour and skill demands for these analyses, it also allows for data from different tests and operators to be easily compared. Thus, operators are able to compare all results and reports, and better monitor changes in substrate energy content over time and with each delivery.

Take control of selecting and pricing substrates

The high quality of the data obtained from the AMPTS II Light can be used to extract important kinetic information of the degradation process, which in turn can be used for selecting and pricing substrates according to their true energy content of biomass. This, in turn, will help biogas operators and substrate suppliers to better control their substrate economy, having a positive impact on overall profitability.

Outstanding real-time performance

The AMPTS II Light is an efficient analytical instrument for conducting various anaerobic batch fermentation tests including biomethane potential assays in real time, having sampling, analysis, recording and report generation fully integrated and automated. A multi-channel analyser consisting of six parallel reactors and the same number of measurement channels (flow cells) attached to a data acquisition system, allows for the real-time investigation of different samples.

Temperature and pressure compensation

The real-time temperature and pressure compensation feature of the AMPTS II Light ensures that the impact of measurement conditions can be minimised and data presentation standardised. The temperature and pressure of gas are measured every time a flow cell opens, allowing the user to derive exact kinetic information compensated for any variation of ambient temperature and pressure over time, while considering the vapour content of the gas. The normalised volumes are presented under dry conditions at 0 °C and 1 atm.

Network ready and easy access

The AMPTS II Light is designed to allow easy access from a remote location. Through the use of standard protocols and connections, the AMPTS II Light behaves like any other unit on an internal network, secured by a user-definable password. All interactions with the software are conducted through a web browser using any computer. Thus, experiment monitoring can be carried out with any kind of smartphone or tablet device.

Stable and reliable operation

The internal software of the AMPTS II Light runs on an embedded ARM CPU utilising the Linux operating system. This provides for an unmatched stability, data protection and minimum downtime. Thus, users will never experience data loss under normal operating conditions, which is always a risk with PC based solutions. Software updates issued by Bioprocess Control can be installed by the user in a controlled and easy manner.

A software application designed for anaerobic batch fermentation tests

The AMPTS II Light web-based software application has been specially designed for carrying out biomethane potential and anaerobic biodegradability tests. This application, which is easy to understand and navigate, allows users to set up an experiment, monitor its progress and download the results with little effort.

Moreover, all data is in a format that allows for easy analysis. The AMPTS II Light software application is simply a natural extension of an already universal hardware platform that has been designed for carrying out biomethane potential and anaerobic biodegradability tests.

A simple and intuitive experiment setup

The Experiment Settings feature of the software application allows users to prepare an experiment by calculating and setting up individual data for each batch test. The user enters values for the total amount of sample, volatile solids (VS) or COD content of inoculum and substrate, inoculum to substrate ratio, total reactor volume, and expected CH4 content of the produced gas. The software then automatically calculates and generates experiment guidelines for the amount of substrate and inoculum needed in each batch test.

Total control throughout an experiment

The Control feature of the AMPTS II Light software application allows users to control both the mixing of reactors and status of each batch test in real-time during an ongoing experiment. Users can control the interval, speed, rotation directions and on/off time of mechanical agitation to ensure each reactor is operated under optimum mass transfer conditions. Users can also easily start, pause and stop data acquisition of an on-going experiment at any time by means of a simple to use cell control feature, which also indicates the status of a cell at all times. Overall, this allows users to have optimal control of all reactors and batch experiments at all times with the simple click of a virtual button from the software user interface.

See your experiment in real-time and anywhere

The Graph feature of the AMPTS II Light software application and embedded web server allows users to see their experiment in real-time and from anywhere. Users can easily monitor the accumulated gas volume and flow rate of each reactor in real time by selecting and viewing only the one they wish to see. Moreover, all values displayed are, if selected, adjusted for gas solubility and/or initial headspace composition and all gas volumes normalized to 1 atmospheric pressure, 0 °C and zero moisture content. This flexibility and precision allows users to always know the status of an experiment, as well as the data being produced.
